1. Qhov xwm txheej tam sim no ntawm kev siv cov peev txheej ntawm cov hlau slag:

Cov hmoov hlau slag tau suav nrog rau hauv tus qauv hauv tebchaws ua cov cement sib xyaw ntev lawm. Muaj ntau qhov kev sim sib piv tau ua pov thawj tias: Thaum thaj chaw tshwj xeeb ntawm cov hmoov hlau slag ntau dua 420m2 / kg, nws cov haujlwm zoo ib yam li cov slag cua sov tawg. Kev sib xyaw ua ke ntawm cov hmoov hlau slag thiab cov hmoov slag tsis tsuas yog txhim kho qhov sib piv ntawm cov hmoov hlau slag hauv cov hmoov sib xyaw, tab sis kuj nce qhov hloov pauv ntawm cov hmoov sib xyaw rau cement raws li kev ua kom ntseeg tau tias kev ua haujlwm ntawm cov pob zeb, yog li txo cov nqi npaj ntawm cov pob zeb. Nws tuaj yeem txo qhov kev hloov pauv ntawm cov khoom sib txuas thiab txhim kho qhov kev tiv thaiv tawg ntawm cov khoom sib txuas. Qhov no qhia tau tias cov khoom hmoov hlau slag muaj kev cia siab zoo hauv kev lag luam. Tam sim no, qhov ruaj khov ntawm cov hlau slag raug txo qis vim muaj CaO thiab MgO dawb. Cov ntsiab lus ntau ntawm cov hlau oxide ua rau muaj teeb meem ntawm kev sib tsoo, kev siv hluav taws xob ntau dua ntawm cov hmoov slag, thiab qhov nyuaj ntawm kev ua cov hmoov hlau slag. Yog li ntawd, qhov ntim muag khoom ntawm cov hmoov hlau slag yog me me, uas kuj ua rau cov hmoov hlau slag dhau los ua kev lag luam tshiab uas yuav tsum tau tsim.

2. Kev sib tov ua vaj tse muab qhov chaw rau kev siv ultrafine steel slag sib tsoo:

Kev sib xyaw ua ke ntawm cov pob zeb ua vaj tse yog qhov kev hloov pauv loj hauv hom kev tsim khoom ntawm cov haujlwm tsim kho, thiab qhov sib piv ntawm cov pob zeb ua vaj tse sib xyaw ua ke qhia txog qib kev tsim khoom lag luam hauv lub tebchaws. Kev xyaum qhia tau hais tias kev siv cov pob zeb ua vaj tse sib xyaw ua ke tuaj yeem ua rau muaj kev tsim khoom ntau dua ob npaug, txuag cov cement 10% ~ 15%, txo cov nqi project li 5%, thiab tuaj yeem ua kom zoo ntawm project, txuag thaj av tsim kho, txo cov plua plav paug, kom ua tiav kev tsim kho ntsuab. Kev tsim cov pob zeb ua lag luam txhawb nqa kev tsim cov hmoov slag thiab nthuav dav kev lag luam ntawm cov hmoov slag. Tuam Tshoj lub Hoobkas sib xyaw ua ke tau tsim tsa xyoo 1980, pib hauv Shanghai, Jiangsu thiab lwm qhov chaw, vim yog kev nthuav dav ntawm qhov loj ntawm kev tsim kho, tshwj xeeb tshaj yog vim kev txhim kho sai ntawm kev tsim kho cov nroog ntug dej hiav txwv sab hnub tuaj, ua ke nrog ntau txoj cai txhawb nqa thiab kev ntsuas los ntawm cov tub ceev xwm tsim kho, yog li ntawd lub nroog cov pob zeb ua vaj tse sib xyaw ua ke nce 15% ib xyoos. Vim tias tus nqi ntawm slag thiab steel slag qis dua li ntawm cement, cov pob zeb sib xyaw nrog slag thiab steel slag yog pheej yig thiab tsim nyog rau kev siv rau hauv cov pob zeb ua lag luam sib xyaw ua ke. Cov pob zeb ua los ntawm kev sib xyaw cov slag thiab steel slag nrog cement, pob zeb thiab xuab zeb daj muaj qhov zoo ntawm lub zog lig siab, cua sov qis, tiv taus kev hnav zoo thiab lub zog sib txuas nrog cov hlau tuav. Nws yog qhov tshwj xeeb tshaj yog rau cov tsev siab, DAMS, tshav dav hlau, lub hauv paus loj tob thiab cov haujlwm hauv qab dej. Tam sim no, cov pob zeb muaj zog heev feem ntau yog npaj los ntawm kev sib xyaw silica tshauv thiab cov neeg sawv cev txo dej ua haujlwm siab, tab sis qhov tsis muaj silica tshauv raw cov ntaub ntawv thiab cov neeg sawv cev txo dej ua haujlwm siab kim, ua rau tus nqi ntawm cov pob zeb siab. Nrog rau qhov xav tau siab dua thiab siab dua rau cov yam ntxwv ntawm cov pob zeb hauv cov haujlwm tshwj xeeb loj, qhov kev thov nce ntxiv rau cov pob zeb ua lag luam tau qhib kev lag luam dav rau kev siv ntau ntawm slag thiab hmoov hlau slag. Tib neeg nkag siab txog cov yam ntxwv ntawm slag thiab hmoov hlau slag, cov khoom siv hauv tsev tshiab, kuj tob zuj zus. Nrog kev txhawb nqa thiab siv cov pob zeb ua lag luam hauv lub tebchaws thiab kev siv cov qauv hauv tebchaws ntsig txog cov khoom siv hmoov slag thiab hlau slag, thiab kev siv cov cai xws li txwv tsis pub sib xyaw cov pob zeb ua vaj tse ntawm cov chaw tsim kho hauv nroog, kev ua lag luam ntawm slag thiab hlau slag hmoov yuav loj dua, thiab nws siv yuav nyiam ntau dua.

3. cov txheej txheem npaj thiab cov khoom siv ntawm cov hlau slag micro-hmoov sib tsoo ntsug tau nrov thiab siv

Tam sim no, cov thev naus laus zis sib tsoo ntsug siv los sib tsoo cov hlau slag micro-hmoov thiab tsim cov khoom uas hloov cov cement clinker uas muaj zog heev, uas yog cov thev naus laus zis tsim khoom siab heev hauv kev lag luam. Yav dhau los, feem ntau slag, hlau slag thiab cement clinker, gypsum, thiab lwm yam ua ke, raws li qee qhov kev sib tsoo rau hauv kev sib tsoo ntawm cement. Vim yog qhov tsis zoo ntawm slag thiab hlau slag, kev sib tsoo tsis tuaj yeem sib tsoo zoo heev thaum sib xyaw nrog cement clinker, nws cov kev ua tau zoo tsis tuaj yeem tsim kho tag nrho, thiab qhov ntau thiab daim ntawv thov ntawm slag thiab hlau slag raug txwv rau qee qhov. Hauv kev npaj cov hmoov ultrafine los ntawm hlau slag ib leeg, Jiangsu hlau thiab hlau lag luam yog nyob rau pem hauv ntej. Ntau lub tuam txhab hlau sawv cev los ntawm Changzhou Zhongtian Hlau thiab Hlau tau tsim cov kab tsim khoom tshwj xeeb hlau slag ntsug sib tsoo. Raws li lub chaw tsim khoom hlau slag micro-hmoov ntsug zeb, HCM Machinery muab kev txhawb nqa hauv txoj kev sib tsoo hlau ultrafine thiab cov khoom siv ntsug zeb tseem ceeb. Nws cov yam ntxwv kev siv tshuab yog cov hauv qab no: kev xaiv cov hmoov hlau slag sib tsoo ntsug, nrog cov thev naus laus zis siab heev, kev tsim khoom txhim khu kev qha, cov yam ntxwv ua haujlwm siab, nrog rau lub tshuab zeb ntsug los tsim ib tuj ntawm thaj chaw tshwj xeeb ntawm 400m2 / kg ~ 500m2 / kg slag, hmoov hlau slag, dua li cov khoom siv pob zeb ib txwm muaj ntawm tib qhov hnyav ntawm hmoov txuag hluav taws xob 30% ~ 50%; Cov hmoov zoo ntawm slag thiab hlau slag yog sib xyaw ncaj qha rau hauv cov pob zeb, uas txuag tau cov cement thiab yog li txuag tau lub zog siv ntawm kev tsim cement. Slag, cov txheej txheem sib tsoo hlau slag, tuaj yeem hloov kho qhov zoo ntawm cov khoom raws li kev xav tau ntawm kev ua lag luam. Nrog rau kev nce ntxiv ntawm slag thiab hlau slag hauv cov pob zeb, qhov kub thiab txias ntawm cov khoom ua rau cov pob zeb tuaj yeem txo qis, uas tsim cov xwm txheej zoo rau kev txhim kho kev ua tau zoo ntawm cov pob zeb nrog kev siv hluav taws xob tsawg dua. Cov hlau slag yog sib tsoo los ntawm cov hmoov sib tsoo ntsug, thiab cov khoom siv yog sib tsoo hauv qhov chaw noo noo ntawm qhov kub siab (100 ℃ ~ 300 ℃). Feem ntau ntawm cov calcium oxide dawb thiab cov magnesium oxide dawb hauv cov hmoov hlau slag micro-hmoov tau hydrated rau hauv cov calcium hydroxide thiab magnesium hydroxide uas muaj zog heev. Tsis tas li ntawd xwb, vim muaj cov slag thiab cov hlau slag hauv cov pob zeb ua vaj tse, cov tshuaj tiv thaiv ntawm cov alkali aggregate tuaj yeem txo tau zoo, cov kab nrib pleb me me ntawm cov pob zeb ua vaj tse tuaj yeem tiv thaiv tau, thiab lub neej ntawm cov tsev tuaj yeem ntev dua. Yog li ntawd, cov pob zeb sib xyaw nrog cov hmoov slag tau txais tos los ntawm kev lag luam kev tsim kho rau nws cov yam ntxwv tshwj xeeb. Kev sib tsoo hlau slag ib leeg tuaj yeem siv ua khoom rau kev tsim cov pob zeb ua vaj tse thiab sib tov raws li kev xav tau ntawm kev ua lag luam, thiab kuj tuaj yeem hloov kho raws li qhov xav tau los kho qhov zoo thiab qhov sib tov kom raug teeb tsa rau hauv cov cement rau kev muag khoom.
